Kubota L225, L235 Sold
OK.... Got my L235 running. Purchased as a unknown damage tractor that suposedly ran when it was traded in for a new tractor. It was started at the farm..... dealer thought it sounded good enough to take in on trade. Somehow then dealer decided they didnt like it and one of their Salesmen took it home with intent to fix it. (yeah right... I dont trust salesmen)

When I listened to the engine get spun w/out firing there was a knock that sounded up high in the engine. Not HORRIBLE but a knock. Tractor was an hour away from home. Took gamble and bought it. On my way home I remembered I'm an idiot. I did not check the oil.

Tractor delivered by seller.. (part of sell price) NO OIL.

Today took another gamble. Put in some diesel lube oil that was on sell. Put water in the Radiator. Cleaned fuel filter and fixed the crack in the plastic Bowl. drained the tank since did not know how good the fuel was. Put some not to old good Kero in the fuel tank. Replaced content of the filter bowl with Lubramolly diesel purge. Replaced injector bleed/overflow lines. Jumped battery to spin the motor and bleed injector lines. Twas a PITA.
Spun engine with oil in it. hmmm.. knock there but less.

1. while trying to bleed injector lines noticed the injectors move some. They have some free play in both directions. Seems odd to me. Had to hold them still with one wrench while loosening injector line cap. Should they be loose?

2. Engine Runs... sounds like it is nailing some? video attached is sound at idol, half throttle and near full throttle. NO LOAD in neutral. Let me know what you think by the sound of it

3. Discovered no oil in tranny either. grrr. Its like the dealer started to service it and then decided to stop there. Anyway; with out shutting it down so not to have to fight to restart it.... we filled the tranny 1/2 to 3/4 full with Gear oil. Friend had about 3 gal of synthetic he had aquired so that is what went in there. Will try to get some more synthetic to match.

4. Gears ground some like clutch not adjusted well and with clutch in and Tractor in gear it would still move some. We adjusted it and got rid of that issue. Sound about right?

5. Broke apart the Decompression pull cable cause it was rust welded together. Somehow saved the pull and about 1/2 the width of the cable. A portion of the inside of the cable pulled out of the Kubota sheath. Replaced the Kubota sheath with a remains of a basardized new chock cable one. Slide the remainder of the Kubota cable and knob into it and whala.... once again have a Docompression pull knob.

Thanx in advance for any help/advice etc.

Wow!! Sounds like you on the right path. Look forward to to seeing your results.

1. No, should be tight to overcome the injector required pressure to inject fuel into the cyl.
2. It is hard to tell without being there in person. At first I thought it was normal, but upon listening again it seemed a little harsh. Not sure.
3. Lubrication is key, but there should be some explanation of where it leaked. I would keep a keen eye on the ground below.
